Chickenpox is an acute infectious skin disease caused by varicella-zoster virus infection, mostly in children, and may have a prodromal manifestation for a few hours to 2 days when it first occurs. Usually a few hours or a day after the onset of fever, the patient may develop a red rash on the body that is small, perhaps only about 0.5 mm in size, and resembles a small red dot. A few hours to a day later, the rash may turn into a herpetic rash, which is oval in shape, about 3-5 mm in diameter, the size of a grain of rice or a green bean, and easily broken, with pus flowing out in clear, clear water after breaking, which may become cloudy later. The rash and herpes are mostly from the trunk, gradually spread to the extremities and face, mostly centripetal distribution, that is, more trunk, less extremities. 1-2 days later the blisters from the middle began to dry up and began to crust, a few days after the scabs fall off, generally do not leave a scar, from the onset to healing of the entire course of the disease is about 1-2 weeks. Patients with chickenpox can show symptoms such as fever, headache, cough, sore throat, loss of appetite, muscle aches and pains, which are more similar to the flu, and patients or their families should pay attention to avoid confusion. The patient or his family should be careful to avoid confusion. Because chickenpox is highly contagious, once diagnosed, isolation should be strengthened until the herpes is completely crusted over, and treatment is based on medication. For patients with severe symptoms or complications, antiviral treatment can be used under the guidance of a doctor. During treatment, care should be taken to ensure clean skin and avoid scratching to prevent secondary bacterial infections.
